README

Usage:
 -capture cfile with usrp:
    $ capture.sh <frequency>
 -run go.sh on this file:
    $ go.sh <file.cfile> 


* Configuration parameter for decoding a certain timeslot:
  Single digit (Timelslot) followed by the configuration, for example:
     0C : TS0  "Combined configuration", with SDCCH/4 (FCCH + SCH + BCCH + CCCH
                + SDCCH/4)
     0B : TS0  "FCCH + SCH + BCCH + CCCH"
     1S : TS1  SDCCH/8
     2T : TS2  Traffic

* Specifying a key will decrypt all traffic burst (SDCCH, SACCH, TCH)
  using A5/1 before decoding

* Use Wireshark and GSMTAP instead of "gsmdecode"

* Limitations:
   - only TCH_F traffic
   - no decoder besides "toast" for Full Rate Speech
   - single ARFCN only
   - no frequency hopping
